Refrigerator intelligent defrosting control method, controller, refrigeration equipment and storage medium

Abstract

The invention relates to the field of defrosting control, in particular to a refrigerator intelligent defrosting control method, a controller, refrigeration equipment and a storage medium. The controlmethod comprises the steps that a refrigerator compressor enters a defrosting cycle; in the defrosting cycle, when a door of a refrigerator is opened, the defrosting time t of the cycle is graduallyreduced according to the number of times of door opening; when the defrosting time t is reduced to t13, defrosting is conducted immediately; and when the defrosting time t is not reduced to t13, if the fact that chamber temperature is raised to T1 or continuous working time of the compressor is larger than t14 is judged, defrosting is conducted immediately. Considering that the door opening time is too long or a large quantity of heat loads are put in, the temperature in the refrigerator is increased sharply, and the operation time of the compressor is prolonged, whether defrosting is needed or not is judged according to the multiple factors such as the number of times of door opening, real-time temperature of a chamber, and operation time of the compressor during defrosting judgment in the technology, decrease of the refrigeration efficiency caused by too much frost of an evaporator can be reduced through rapid defrosting, and the situation that the heat loads in the refrigerator aretoo large, and the compressor operates continuously without shutdown is prevented.

Description

technical field [0001] The invention relates to the field of defrosting control, in particular to a refrigerator intelligent defrosting control method, a controller, refrigeration equipment and a storage medium. Background technique [0002] For the current air-cooled refrigerators, such as figure 1 As shown, the defrosting method of accumulating the working time of the compressor and the number of times of opening and closing the door is commonly used. When using this defrosting method, the defrosting time of the refrigerator is affected by the basic defrosting time (accumulated working time of the compressor) and the number of door opening and closing. Until the minimum frost interval t3 is reached. The overall defrosting method is relatively single-plate, and cannot flexibly deal with various special situations—such as a single door opening and closing time is too long, or a large amount of heat load is placed in the door, which leads to excessive temperature rise in th...
